This SCS-C02 practice question tests your understanding of identity and access management. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which TWO of the following are valid IAM policy condition keys? (Choose TWO.)
aws:RequestedRegion
Valid condition key for region.
aws:RequestedService
Why wrong: Not a standard condition key.
aws:SourceIp
Valid condition key for IP address.
aws:PrincipalService
Why wrong: Not a standard condition key.
aws:SourceArn
Why wrong: Valid for some services but not a general condition key.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
aws:RequestedRegion
The `aws:RequestedRegion` condition key is valid and used to restrict access to specific AWS Regions. It evaluates the Region endpoint that the API request is sent to, allowing you to enforce that actions can only be performed in designated Regions, such as us-east-1 or eu-west-2.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.

Common exam traps
The trap here is that candidates often confuse `aws:SourceArn` with `aws:SourceIp` or assume `aws:RequestedService` is a real key because it sounds plausible, but AWS does not define these keys in the IAM documentation, leading to incorrect selections.
Detailed technical explanation
The `aws:SourceIp` condition key evaluates the source IP address of the request, which is derived from the TCP connection's source IP and can be used to restrict access to specific CIDR ranges. The `aws:RequestedRegion` key is evaluated against the Region endpoint in the request URL (e.g., `ec2.us-east-1.amazonaws.com`), and it is particularly useful for enforcing data residency requirements by blocking API calls to non-approved Regions. Both keys are part of the AWS global condition context keys and are evaluated at the time of the request.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
